In previous OS News articles, I described how mature computers
up to ten years old can be
refurbished and made useful. One
article identified and evaluated different approaches to
refurbishing. This article tells how to performance tune a mature
Windows computer to make it serviceable again. I hope it will interest
anyone who wants to tune Windows.

I like your sentiment but the article topic really was "how do I tune a Windows machine". Discussion of osX, Linux, BSD, VMX or Plan9 does not equate to "here's something that can improve your Windows performance."

Your not being called a Troll because you profit from pushing another OS but because your continuing to push another OS topic not relevant to the article or discussion.

Imagine a discussion on partition selection and sizes for Linux based workstations and someone keeps chiming in with "well, on my Windows it works like this..."
